    Project mention: Does anyone use sound effects in their dev environment? | news.ycombinator.com | 2024-09-12

  5. Platypus

    Create native Mac applications from command line scripts.

    Project mention: Shoes makes building little graphical programs for Mac, Windows, Linux simple | news.ycombinator.com | 2024-02-23

    For macOS/iOS, you could give Strongbox a try: https://strongboxsafe.com/

    I haven't really looked into it myself, but it seems to be using the same database format as KeePass, and it hooks into macOS's "FIDO provider" API, which makes it accessible to not only Safari but all browsers that use it (which includes Firefox and Chrome on macOS, and probably everything on iOS), without requiring any browser-side extension.
